Application filed April 9',

Thus when the key is inserted into the keyhole of a lock, the spring Will give su'fficiently to pass into the hole, but it-wili frictionally engage the wall of the hole and thus yieldingly hold the key in the lock. The spring will permit the key to bore moved from the lock forcibly, but it will prevent the key from falling out of the lock when the door on which the lock is blaced I is slammed. The spring will prevent 21 0- I cidental removal of the key from the lock and the key will remain in place until it is forcibly pulled from the lock.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily-apparent.
